Circular arc block arrows, from 360º down to 45º, in sets forming full circles.

And, of course, rotations can be applied, either to a grouped circle, or by selecting all of its ungrouped components.

(I find some of these rotations quite interesting and useful - expressive of processes like convergence, dispersal etc ).

To reverse arrow directions:

1. Select a whole grouped circle,
2. Inspectors,
3. Geometry,
4. Flip (horizontal or vertical).

and circles of 9-12 arrows, just in case ...
